That belly cut definitely reduces the possible value greatly as well as the bridge having cuts in it and metal removed. Please remember the vintage market is not what it was five years ago. IMO due to the belly cut on the body you might find more value in parting it out. A safe evaluation would be to add up what you can get for the parts separately and go from their. Too bad about the body and bridge because everything else visually can be recreated. I don't think you'll get a definite statement of saying "it’s worth this much". No one can because it requires the right buyer to want it at the seller's price. It’s not worth anything until someone gives out the money for it. So you might get a price range. Another reason some knowledgeable dealer may be reticent to say even if it was an in hand appraisal is as I mentioned before; the market is not very stable right now.
